I also have a Intel video card and I experienced this kind of behavior
recently. More exactly, its happens about half the times when I suspended my
laptop with kernel linux-image-2.6.32-4-amd64 version 2.6.32-11. Two times,
this even leads to on-disk corruption.
Since, I go back to 2.6.32-10. I still sometimes see this behavior (all
applications failing after resume) but it is far less often.
Regards,
Vincent
